THOMAS C. BELDING, OF CANTON, ASSIGNOR TO THE UNIVERSAL PLOW COMPANY, OF VVOOSTER, OHIO.

PLOW-CLEVIS.

SPECIFICATION forming part of Letters Patent No. 415,016, dated November 12, 1889. Application filed August 5,1889- Serial No. 319,788. (N model.)

To all whom it may concern:

Be it known that I, THOMAS C. BELDING, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and usefullmprovelnent in a Plow-Clevis, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

making part of this specification.

My invention relates to an improvement in plow-clevis and link.

The object is to provide a clevis and link by which a doubletree may be attached to a plow-beam so as to allow the doubletree to vibrate about its pivotal connection with the plow without diverting it from its course.

With these ends in view my invention relates to certain features of construction and combination of parts, as will be hereinafter described, and set forth in the claims.

Figure 1 of the accompanying drawings is a view in perspective of the front end portion of a plow-beam with clevis attached thereto, illustrating my invention. Fig. 2 is a side elevation of same, partly sectional, and Fig. 3 is a perspective of a threaded and trunnioned nut hereinafter explained.

Similar letters of reference indicate corresponding parts in all of the figures of 'the drawings.

A represents the front portion of a plowbeam, to which is secured a chambered crownpiece B, composed of two portions, as ab. Said portions are of the form substantially as shown, having rearwardly-projected arms 6, secured together by a bolt, as f, and arms g, having overlapping perforated portions through which the bolt h is passed, thereby securing the crown B to the beam A. There are also provided in the sides of said crown oblong apertures j,-and inside a screw, as O, is provided having collars it, that embrace the edges of the upper portion of the crown-piece, as shown in Fig. 2. The lower end portion of the screw is supported in a perforation in the lower portion of the crown. A threaded nut, as D, having trunnions Z, is turned onto said screw, as shown in Figs. 1 and 2, the trunnions projected through the oblong apertures j. A draft-loop, as E, is provided, having prongs m, the rear ends of which are pivotally secured to the beam by the :bolt n. Near the front portion of the prong is an oblong aperture 0, in which is placed the trunnions l of the nut D,by which the link is raised or lowered and held in adjustment by the screw 0. For the purpose of this application, I have shown the rear end portion of. the groove cut away to facilitate the removal of the link; but, if preferred, this opening (1 may be omitted, the links made malleable, and sprung over the ends of the trunnions. At the rear side of the front portion of the link E and central thereto is provided a circular depression 19, as shown in cross-section in Fig. 2, and on the frontface of the crown B is provided a vertical groove p, circular in cross-section. The draft-link F is formed of two transverse lobes, the rear one, designated as r, having at its rear portion a spheroid or ball-shaped portion, as 5, having neck portions, as t, diametrically opposite, said neck portion uniting with the arms to, thus completing the rear lobe a". The front lobe v is of the form substantially as shown in Fig. 2. The front portion of the ball 3 resting in the depression 10 and the rear portion against the crown D, will serve to hold the link F in position, forming a pivot about which the doubletree may be vibrated without changing the point of contact or engagement between the draft-loop E and link F, whereby a central line of draft may be maintained and the diversion of the plow from its course avoided.

Having thus fully described the nature and.

object of my invention, what I claim as new, and desire to obtain by Letters Patent, is-

1. The combination, with the plow-beam A, of the chambered crown B, having an adjusting-screw O therein, a draft-loop E, pivotally secured to said beam and screw, said loop having in its rear face an inwardly-projected circular bearing 1), and a draft-link F, having forwardly and-rearwardly projected convex portions to engage thecircular bearing in said loop and the front portion of said crown, whereby the link may be pivotally secured in the line of draft with the plow, substantially as described, and for the purpose set forth. for the purpose set forth.

2. In combination with the plow-beam A, In testimonywliereofIhave hereunto setnly 5 a draft-loop E having oblong side perforahand this 18th day of June, A. I). 1880.
